  • Target start date: 01-July-2024

Your responsibilities

You will be part of :

  • The Beams department, responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the LHC and its injector accelerators.
  • The Accelerator and Beam Physics Group, which is responsible for studying and understanding the beam dynamics over the complete CERN Accelerator Complex through theoretical, simulation and experimental studies. The group provides input and support for machine operations, devising settings and scenarios to optimize the machine performance. It is also responsible for working out concepts and ideas for future accelerators.

In the Applied Physicist – Radio Frequency Quadrupole (BE-ABP-HSL-2024-92-GRAP) position, you will lead the project of characterisation the Radio Frequency Quadrupole (RFQ) for carbon ion acceleration

Specifically, you will:

  • Perform the beam measurements on the RFQ at high frequency (750MHz) that is the pre-injector for a linac-based Carbon Ion Facility;
  • Characterise the proton and carbon source in preparation of the RFQ commissioning;
  • If time permits, study the implication on the folded linac layout of the measurement findings.

Your profile

Skills and/or knowledge

  • Experience with beam measurements;
  • Knowledge of the Radio Frequency Quadrupoles (at high frequency); 
  • Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State.
  • You have a professional background in Applied Physics (or a related field) and have either:
    • Master’s degree with 2 to 6 years of post-graduation professional experience;
    • or a PhD with no more than 3 years of post-graduation professional experience.
  • You have never had a CERN fellow or graduate contract before.

This position requires:

  • Work during nights, Sundays and official holidays.
  • Residence in the immediate vicinity of the Organization’s installations.
  • A valid driving licence.

What we offer

  • A monthly stipend ranging between 6212 and 6828 Swiss Francs per month (net of tax).
  • Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
  • Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
  • 30 days of paid leave per year.
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world’s largest and most complex scientific instruments, they study the basic constituents of matter – fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on
